Phase 3 wing mirrors

[Niall]

If you open up the wing mirrors and inspect the rear of the glass there are two wires soldered (I think) onto contacts on the rear of the glass. If they don't work it is worth checking. Bear in mind that the glass doesn't get hot, just warmer than cold to get condensation off.

Ive found that mine do actually get quite hot!
There is two spade connectors on the back if they are heated. Come on with the heated rear window. If they don't work, switch the rear window on and check for 12v across the 2 red wires in the mirror. If its there, new glass needed.
